The reservoir is now completely full, just in time for the busy recreation season. All boat ramps are available including Mongold. Pretty much any technique will catch fish, but it might take some experimenting to find out what is most effective on the day you're out there. For those anglers without a boat, there are recreation areas in both upper arms of the reservoir that allow for easy bank angling.
The reservoir gets stocked with trout during the late spring and summer. It will be stocked this week with about 6,000 trophy sized hatchery trout. As a reminder, anglers are allowed to keep up to five trout, with an additional five fish kokanee bag limit. Anglers are reporting good success lately.
Also, as a reminder to anglers, fishing for and harvesting Chinook in the lake and the rivers above is prohibited. Any Chinook caught in Detroit must be released unharmed. Make sure you can tell the difference between a Chinook and a kokanee before you get out on the water.
It's always a good idea to check the water levels at the U.S. Army Corps of Engineers website before using the boat ramps. For the latest information on water levels at Detroit Reservoir check with the Army Corps of Engineers' website for more information.
Anglers are encouraged to report their catch on an on-line form. Remember to indicate whether the fish you catch have their adipose fin or not. This information will allow ODFW to manage the fishery for the benefit of both recreational anglers and the resource.
